1. An augmented reality surgical assistance method comprising the steps of:
(a) capturing a radiological image of a patient's anatomy, together with an instrument guide having a radiolucent portion and a radiopaque portion;
(b) computer processing the radiological image to (i) identify at least one boundary of the instrument guide from the radiological image, (ii) determine a centerline of the instrument guide on the radiological image, and (iii) superimpose on the radiological image a virtual medical object (VMO) extending from a distal end of the instrument guide; and
(c) transmitting to and displaying on augmented reality (AR) glasses the radiological image showing the VMO.
